在我的Spring (SWF)中，流不能在任何地方传播并再次显示第一页

Question

我使用Spring (SWF)进行会话类型的页面导航。在该项目中，有一个主流名为candidatemain flow .xml，并有名为候选人流的子流和matriculation. and。当我运行我的项目时，主流开始并将事务处理到名为候选人流的子流，并呈现注册页面。但是我在注册表单中填写了一些数据并将其提交回子流，它不能遍历第二个子流称为matriculation.xml(我认为)并再次显示注册表单，并且这个流步骤"execution=e1s1“再次显示。

这是我的流程的主要定义：

这是候选人-flow.xml.xml：

这是matriculation-flow.xml.xml：

Answer 1

您的评论是部分正确的，但不是验证器，但它需要转换器或格式化程序。尽管我直接通过调用ref类型点(它的值类型变量)来填充数据，但"IdTypeDTO“对象和”性别“枚举作为字符串绑定到其模型类的属性(意味着"candidateModelBean.candidate.idType”属性是引用类型，而我将该属性绑定为字符串)。

因此，我只需为该类型的属性添加自定义格式化程序，如下所示：

public class GenderFormatter implements Formatter<Gender>{

@Override
public String print(Gender gender, Locale local) {
    return gender.getLabel();
}

@Override
public Gender parse(String value, Locale local) throws ParseException {
    if(Gender.valueOf(value) == Gender.MALE) {
        return Gender.MALE;
    } else {
        return Gender.FEMALE;
    }
}

}

并在格式化程序中注册，在well配置文件中注册和配置，一切顺利，并过渡到第2页(candidateRegistrationViewSec.jsp)。然而，由于您的评论，我再次检查并意识到解决方案。谢谢你回答普拉萨德:)

Answer 2

这里有两种可能性。这可以从以下语句中推断出来："..it不能遍历第二个名为matriculation.xml的子流(我认为)，然后再次显示注册表单，并且这个流步骤"execution=e1s1“再次显示”。

将方法包括为post

   <sf:form cssClass="form-horizontal" commandName="candidate" method="post">

1)事件不是由视图candidateRegistrationViewFir.jsp生成的，因此snapshotId(e1s1)不会发生更改。

提交按钮的语法看起来是正确的：

    <input type="submit" class="btn btn-primary" name="_eventId_submit" value="Newer &rarr;"/>

但是为了确保尝试几件事：

要么将按钮更改为(这实际上并没有什么区别)：

    <input type="submit" value="submit" />
    <input type="hidden" name="_eventId" value="submit"/>

或者：

包括javascript函数：

    function submitEvent(eventId)  
    {   
            document.getElementById("candidate")._eventId.value = eventId;  
            document.getElementById("canditate").submit(); 
    }

并包括在联合军事行动计划中：

    <input type="hidden" name="_eventId" value=""/>

并将按钮替换为

    <a href="javascript:submitEvent('submit');"><span>Newer</span></a>

2)有一个注册验证器对模型“候选人”进行验证。如果模型上存在验证错误，则流将位于相同的视图中，因此snapshotId(e1s1)不会发生更改。但是，根据您的评论，方案2被排除在外。
